PROPELLIN G APPARATUS.

To all whom it may concern:

Be it known that I, GUSTAV UNZNER, a subject of the German Emperor, and a resident of New York, county and Statcof New 5 York, have invented certainnew and useful 'Improvements in Propolling Apparatus, of

which the following is a'specification.

The present inventionp'ertains to a propelling apparatus, which can be utilized as a flying machine or can be suspended from a balloon and consists in the arrangement of vertical sets of horizontally reciprocating paddles or wings f which each, at the end pfiitsreoiprocating movement, is capable of t 5 being reversed from vertical into horizontal a position and vice versa'. I Bythe rapid horizontal movement ofthe wingsin vertical position, the apparatus will i 3 propelled forward, the wingsbeing so ar- 2j0 ranged that when in horizontal position, the

entire set ateither side of the frame to which the)"are attached, Will forin anah'n ost unin -terrupted, vast surface, which, during the horizontal movement thereof, will pause a i high compression of: the air whereby the apparatus will be rapidlythrust forward.

,The. apparatus is preferal'ily divided in twohorizontalsections, "in eachof which horizontal; worm spindles w th reversed spindleearries', by means of a peculiarly constructed -nut,a frame that is capable of being "fed; along the sanie,-andjthat at each endisfiprovided"with such vertical set of -wiings, Owing tothe reversed thread, the wan gs in one section will be caused tojinove [in opposite direction to; those in the'fo'ther .K. f seo tion, l urthermore, while inone section, the wings move in vertical position propelling move in horizontal po'sition not impairing the pro polling movement of j the" apparatus l and assume wertical 'position as soo n as the first named wings are reversedi'nto lilori z .)ntal;p.isi tion'. -Contin'ui ng thus toalter- 'natelyi change their position from Vertical i into horizontal andwice versa while moving rapidlyforward -and backward]: the wings .wj'llvperinit the" apparatus of propelling itself a'o in the airi'n the fashion of a, bird. f :1 v

tally reciprocating wings.

, I i v isto ascend. s o threadarerotat velymounted. Each'worm the i other section Patented Dec; 17, 1907 the apparatus so as to cause the wings to,

swing'in reversed direction from one position into the other.

Similarly to l the horizontal l sections, I "arrange at each end of the frame two vertical isection'su in which vertical worm spindles with reversed thread are rotativelymounted,

carrying vertically reciprocating frames in which horizontal sets of wings, of similarconstruction as those in the horizontal sec ,tions, are provided. These wings, likewise,

are capable of swinging from vertical into horizontal position, and are designed to propel the apparatus upward and downward, The operation of these vertically reciprocatingwingsis'similar to those of the horizonv v hen the pro elling apparatus is suspended from a ba loon, the vertically reciprocating wings may be dispensed with, and

for this purpose the vertical worm'spindles may be provided with suitable'couplings to allow of the same being easily thrown out of gear, If, however, desired, these vertically reciprocating wings can be utilized for as :cending or descending, and the same will thus dispense with the necessity of carrying ballasts to be thrown out when'the machine In caseof theniotor being out'of order, the

, i vi'ngs in the horizontal and vertical sections 'nrayall be brought into horizontal position so "as"to a'ct as aparachute which will prevent the {apparatus fronisinking too rapidly.

' One of the main features of" my invention,

is the means whereby the reciprocating frames'in the horizontal and vertical'sections of thappar'atus are caused to rapidly move along the worm spindle,-'and whereby the frictionbetwe'enthe moving parts is reduced to a minimum.- Owing to this feature, only very small power isnecessary for propelling the apparatusg V According to the size of the machine the number of wings in each set may be v'afied. It is evident that the longer the worm spindles, the moreeflective will be the apparatus, To make my invention more clear, "the .same is illustrated in the accompanying drawings, in which similar referenceyletters denote corresponding parts and in which Figure 11 1s asid e'view; Flg; 1 ..is a topplan view the propelling apparatus; Fig.2; a

' one section of the frame are in horizontal position, the paddles 1n theothersectron of the frame are in vertical position and vice versa,

My apparatus consists of a rectangular raine in the other section 4 moves 1n. oppo frame A composed of horizontal and vertical tubes 1 and-2and is divided into two 'sections 3 and 4, the left and righthand sections, there being formed a space 5 between the 'two sections for the accommodation of .a suitable mo tor 6 andtransmission'm-eans; Extending centrally and longitudinall through each section of the, rectangular ame are worm s indies 7, 8 with reversed threads, these'spinles being each supported in cross-bars 9 (Figs. 2 and 4) by means of suitableballbearings 1O indicated'by dotted lines in 1'".v Both spindles are connected by a suita le coupling 11 and may be driven from the motor bya' transmission belt 12 guided overa pulley 14 and a countershaft pulley 13 of any suitable construction whichis to allow of the spindles .--being alternately drivenin one andthe other direction. .Y

At each end of thefr'ame, two vertical sections 15, 16 are arranged in which similarly to' the horizontal spindles vertical lspindles 17, 18 are mounted inball bearings and are driven from the horizontal spindles-by means of cog wheels21, 22. 19. 2O denote couplinlgs whereby the vertical s indles can be"read' y coupled with one anot er and with' the. hor1- zontal s indles. f g' i In eac 'of the horizontal sections 3 and 4 of the frame, a reciprocating H -shaped frame 23' (Figs. 2 and 3) is arranged'which is mounted on the horizontal spindle to be horizontally fed along the latter andiwhich carries at its four ends,'g'uide rolls 24 that run between lon itudinal guide tubes 25 suitably secured to t e frameand that serve to guide the frame 23in its longitudinal movement;

To allow of a forward and backward feedof the frame 23 along the horizontal spin- -dle,- the: same-is provided atits center with a sleeve 26 (Fig. 9);.which closely fits around the thread of.the.'s indle and in which balls 2 7 home between-t e thread and the sleeve areinclosed. These balls are secured in osition by 'set screws 28 workin in ob ique bores made in the sleeve 26. fire/sleeve toether withthe balls thus forms a nut for the ame 23 whereby, during rotation of the 55 spindles, the'frame will-be caused to move in horizontal direction. 1

. To each sideof theframe 23 a verticalset of wings or. paddles 29 are secured which serve for the. urposeofpropellinglthe appa= ratus forward? and backward- -T ese Wings 29 are so constructed as to be capable of be.- ing reversed from the vertical into horizontal position at the ends of the reciprocating movement of the frame, the a'rran ement 65 being such, that while one set of pa dles in site direction. .Owing to the ball bearing of "the frame 2 mm serves as a nut for the spindle, the frame-will move with great ease along the. latter,'- the friction-being reduced toaminimum. The-attachmentof the paddles'to th'e'side bars ofthe frame 23 is attainedin the followin' manner: Each paddle is provided with'a ho low cylindrical neck 30 which at its rear end is formed to'a circular disk31. Borne and secured within the neck 30 is a bolt 32 which projects outward from said neck andis secured in the side bar of the frame 23. Between-tne 'sidebar of the frame and the circular disk '31 a disk 33 is arranged forming with the disk 31a ball bearing 34. Owing to the ballbearing 34 th. paddle is allowe to easily swing around the bolt '32 from l1O1i zontal intofvertical position, and vice'versa. lhe disk 31 at the end of the neck 30 of each paddle isprovided with longitudinally pro- ,sjectin pins 35,- 35 arranged diametrically to eac 7 other and the rear ends of saidpins jengagefiinto'circularly curved slots 36, 36 arranged in the. opposite disk 33, whereby the swinging movement of the wings will be .limited to an angle of 90?. The forward end of each of said pins serves for reversingthe paddles from one positioninto the other as will hereinafter be fully, specified. Normally, that is, when the wing is either in horizontal or -vertical position, its p'ins'3'5, 35 will be located at the opposite ends in the respective slots 36., 36 as indicatedby dotted lines in Fi 8 and will be held-in this position by suitable spring .actuated guide pieces 39 which'are secured in the frame 23 and which bear against the outer surfaces of-said pins. The ide piece 39 consists of a socket 40 so cure to the frame 23, in which telescopes r spring actuated tube shaped piece 41. The outer endof said piece is formed to an enlarged head piece 42 that is adapted to rest against the pin 35 or 35. v Themechanism for reversing. the position of the wings at the ends of their reciprocating movement within the horizontal sections of the frame consists of vertical adjast able bars 43, which are secured to the vertical end tubes 2 in each section and which are provided with longitudinally projecting shoulders 44 extendin in the path of the reciprocating wings. hen the frame 23 carrying the wings 29 approaches the end of its horizontal movement, the shoulders 44 will strike against the pins 35, 35 and swing the same towards the opposite end of the slot within the disk 34 thereb reversing the po- Sl'OiOII of the paddle from. orizontal mto vertical position or vice versa.- In each set, the

wings are arranged close to one another, so" that when the same are in vertlcal position,

cause a high compression of the air, whereby.

the apparatus will be propelled forward.

For steering the apparatus,'.the vertical bars 43 are, as mentioned, adjustable in ver tical position and for this purpose the'same are secured to'the tubes 2.by pins or screws 45 that pass through vertical slots 46in the.

bars. 'The lower ends of said bars bear against springs 47 suitably attached to the frame, which tend to throw the'same into initial position. Rigidly secured tothe bar 43 is a pin 48 which projects rearwards through a vertical slot 49 in the tube 2 of the frame, as shown in Fig. 12, and cooperating with said pin 48 aresliding bars 50 extending longitudinally Within the sections of the frame. The upper edge of each bar 50: is

formedwith oblique shoulders 51 which are 2 5 When the bars are moved in longitudinal. di-

rection, either forwardor backward, .the

is constructed as follows: Suitably supported on a cross bar 52 in the frame brackets.53'.are

arranged brackets 55 which are formed'attheir upper ends with guide grooves or chan+ nels 54 that at their ends are provided with notches 54 (Figs. 3 and 10). Fulcrumed-to' the lower ends of said brackets at 55 are bell crank-levers 56one end of which is adapted to support a spring. actuated rod 57'movably borne in a sleeve 58-. arranged at a suitable point-of the slidingbar 50.7 Thisrod 57*is provided with a cross arm159 one end "of whiclncarries aguide'rol'l 60-:adaptedlto slide.

in th' groove,54land the otherend forms acatch which, when-the rod 5!? is lifted-so that the guide roll 60 isdisenga ed from the notch 54, will come into-the v ated pin 62 carried-1i y the reciprocating frame 23 so as to become engaged with said pin 62 and to be carried along withthe frame 23. During the lon itudinal .movement of accordingly steered. 6 0

frames 63 which are guided along the vertical side to bes2. meansof guide rolls. (Fig.

4). ilhes'e v ertically, movable frames 63 are 65 each provided with a setof wingsfidthat are adapted to rest underneath the pins 48;.

at ofa spring 'actuthe bar 50 its shoulc ers 51 will operate the pi'ns 48 so.as to lift or lower the bars 13; whereby the wings will be moved either fromf right to left or vice versa; and the apparatus- "The' apparatus, as described and At. each end of the frame-A inthe vertica sections 15, .16, are vertically reciprocating of the same construction and are 0 era-ted in a similar manner as the wings 29 o thehorizontally movable frames 23. The latter are centrally mounted on the-spindles 17, 18 by I means of the above described nutconsisting of the sleeve 26 and balls 27, shown in Fig. 9

- 'whereby the frames 63 will be-fed along the spindles 17, 18, whenthe latter are in motion. The paddles 65 of the frame 63 are likewise capable of being reversed from the horizontal position into vertical position and vice versa, which reversion takes place at the ends of the reciprocating movement of the frames 63. The pins 66 of said paddles which correspond to the pins 35 ofthe horizontally reciprocating paddles are operated by fingers or shoulders 67, 67 that project inward from cross bars 69, 69, 70, 70 arranged in the vertical sections of the frame. These-shoulders are arranged in the path of the pins 66 of the ver-- ti'cally reciprocating paddles, so that when the frames 63 reach the end position of their ,vertical movement, the fingers or shoulders- 67 in striking against the pins 66 move the latter around an angle of 90 and thus re- 'verse'the position of the paddles. In these vertical sections, the frames '63 also move in o posite directions owing to the. reversed tliread'of'the. spindles 17, 18, and While the paddles in one section are moved in horizontal position, those of the other section are ,moved in vertical position and viceversa.

By the rapid downward movement of the frame 63 in either of the vertical sections, the

' wings in horizontal position will cause a com pression. of the air therebyeflecting' the ascending movement of the apparatus. While the wings in one-s'gectionwill move in hori- 'zontal'position, those in'the'oth'er section .will movein vertical position and vice versa, sothat the ascendingmovementf will not be counteracted. Infthewcase when this propelling apparatus is applied to a balloon, the vertical spindles may be thrown out of gear with the horizontal-s indles,- so as to be at 'rest,- and the wingswlienin horizontal position will actas' a parachute reventing' the balloon from sinking too rapidly.

' At the upper end-of the frame of the apparatus, a-platform' .71-for passengers, with a railing 72 may be arranged, :(Figs. 5, 6) over which a roof 73 of suitable material maybe arranged" that willfnot only 'serve to cover the assengers, but also serv e as a parachute.
